I hammered InfoSoft with questions BEFORE I purchased the GRID and Rushabh Patel of Siddhi InfoSoft patiently answered my questions one by one because they did not have enough documentation posted...simple information like, Is it Mobile Compatible (it is), Browser Safe (so far, yes), etc.
FYI: After purchasing you will get download link to download the product zip. Extract the zip file, which contains 1.5, 1.7 & 2.5 Joomla versions, and inside those you will get a documentation doc file.
And, because they are new, they only have a fledging Forum. I posted my questions there originally and anyone who does have questions should do the same so their Forum will become more helpful.
In the interim, I cannot believe how they quickly addressed & solved every single tweak needed for my environment. So.
--Great Support but remember they're based in India (Time zone).
--The admin area is simple and effective.
--If you want attractive thumbs that can link to various destinations, show Title info AND can optionally open in a Lightbox effect, this is the only extension I know of that accomplishes this.
Great job, Siddhi InfoSoft!
